  • Elevator linear motor bus bar
    Patent number: 5090516
    Abstract: An elevator is driven by a linear motor having a flat secondary element comprised of a plurality of segments which extend the length of an elevator rise. The segments of the secondary element are connected by a bus bar which overlaps joints between each adjacent segment by enclosing an end portion of each segment. The bus bar, conducts current across the joints, provides a surface for guide rollers which maintain an air gap between the secondary element and a primary element, and minimizes relative motion between adjacent segments of the secondary element.
